I have a powerbank compatible with USB c and power delivery that has no more than a year. With smartphones do the quick charge well, but recently I tried to charge my T470s using USB C with it and doesn't charge anymore (Used to work). When is connected PB and the T470s makes a led signal but rapidly turns off.
How can I diagnosis the hardware? I want to make sure is a hw issue and it's the ThinkPad.

USB C Power delivery charge stop working on T470S
Re: USB C Power delivery charge stop working on T470S
Welcome to the forum.
Do you have a normal USB-C charger that connects to a wall outlet (a genuine Lenovo or other brand)? You could see if that still works.

By changing the usb cable now works. Any case is strange that usbC to Usb cable works with smartphone and with laptop (before), but no now.
